(cwdstuff::set): Take native NT path. * ntdll.h (struct _TEB): Typedef. * path.cc (mount_info::conv_to_posix_path): Add variant taking wide char DOS paths. (symlink_info::posixify): Simplify concatenating cwd and relative path. (hash_path_name): Drop special relative path handling. (chdir): Drop special "drive only" handling. Call cwdstuff::set with native path. (cwdstuff::get_hash): Remove. (windows_system_directory): Remove. (_upp): Remove. (get_user_proc_parms): Make inline. Get PEB pointer by calling NtCurrentTeb. (cwdstuff::init): Simplify. (cwdstuff::set): Rework to handle incoming native NT path. Workaround a Vista problem with CWD handle in the user process parameter block. (cwdstuff::get): Simplify locking. Accommodate type change of win32. * shared_info.h (mount_info): Add declaration for new conv_to_posix_path method. * strfuncs.cc (sys_wcstombs): Return correct length of created multi-byte string.
